1. Field of the Invention
The invention relates to a method of emptying a container for the storage of fish, such shellfish, which are in the container together with water, the emptying taking place through a pipe provided in the bottom of the container, a medium being supplied into the container during emptying.
2. The Prior Art
Containers of this type, which may be made of plastics, are used for the ripening (maturing) of, e.g. shrimp. Typically, they have a size of 660 or 1000 litres and are emptied after ripening is completed simply by tilting.
For operational reasons, it is desirable to be able to ripening shrimp larger containers, e.g., containers having a capacity of 12000 litres. However, containers of this size are not easy to handle in connection with emptying where the container is to be tilted. It would therefore be an advantage if the container could be emptied through a pipe provided in the container. However, it has been found that, with such large containers for the storage of shrimp in water, emptying through the pipe will rapidly result in clogging, as the liquid will leave the container faster than the shrimp.
A container having a pipe at its bottom is known from DD Patent Specification No. 61451. In this method, a mixture of fish and water is pumped from a pipe located at the bottom of the container vertically upwards to a conveyor belt above the container, where water is conveyed back to the container, while the fish are transported further on.
Accordingly, it is an object of the invention to provide a method of emptying the initially mentioned large containers, which requires fewer installations, while maintaining a minimal risk of clogging.
The object of the invention is achieved by a method wherein fish and water are removed via a pipe at the bottom of the container and medium is concurrently supplied to the container, the medium being air which is supplied through holes provided near the bottom of the container.
Hereby, emptying takes place through the pipe as a very homogeneous uniform mass without the pipe becoming clogged.
As mentioned, the invention also relates to use of the method.
The invention will now be explained more fully with reference to the drawings, in which;
With a view to avoid clogging of the container, the bottom and optionally the inclined walls are formed with holes 3, 7 through which a medium, such as air may be conveyed, indicated e.g., by the reference numeral 8. The holes are located on opposite sides of inlet opening 4 a and are located along the length of the (elongated) container.
As will be seen in
Alternatively, a pipe distribution system (not shown) may be lowered into the container for the supply of water or air under pressure, which may e.g. be an advantage if existing containers are to be upgraded.
Instead of a pipe or hose 6 connected to the bottom wall 4 a the pipe or the hose may be disposed inside the container, as shown by the reference numeral 2.
When the contents of the container are to be emptied, water or air is optionally supplied via the hole-shaped pattern. It is ensured hereby that the pipe 2 of the container does not clog when its contents are discharged from the pipe 2 in the direction of the arrow 9.
The rate of this discharge may generally be increased if suction is applied to the pipe 2.
The container may be made of plastics or metal and have a size of e.g. 12000 litres.
